Twilight Exclusive: R-Pattz Goes Kristen-less to Eclipse Wrap Party

There’s still about a week of shooting to go on Eclipse the third installment of the über-hot Twilight Saga, but that didn’t stop 500 people from celebrating the near-completion of the vampire flick on Saturday night in Vancouver. And while the film’s marquee star, Robert Pattinson, managed to put in an appearance, his leading lady Kristen Stewart was noticeably absent.

The bash, hosted by Eclipse director David Slade, was held at the Vancouver Aquarium in Stanley Park. And part of the reason for throwing the party before filming is actually completed, explained Slade to partygoers, is that he had to wrap filming on five of the movie’s actors today — including Elizabeth Reaser, Kellan Lutz and Taylor Lautner — so the fictional town of Forks, Wash., suddenly got a lot less crowded.

The event began at 8pm on Saturday, and the hundreds of guests got to nibble on sushi and drink freely from one of the three open bars set among the aquarium’s mammoth floor-to-ceiling displays that are home to more than 300 species of fish and other aquatic life, including a 31-year-old dolphin named Laverne, eight sea lions, dozens of otters and six beluga whales.

R-Pattz, dressed in his standard baseball cap and dark shades, finally arrived solo around 10pm and according to guests inside the party he only stayed for approximately 45 minutes before hopping into a cab by himself.

Many invited guests, who were only allowed to bring one friend, and who were required to present photo ID at the door for security purposes, had expected that Kristen would pop her head in to say hi. But alas, she was a no-show.

“It’s not like she has anything else to do in Vancouver,” quipped one partygoer to OK! about the actress’ absence.

One Twilight biggie that definitely made his presence felt was co-star Jackson Rathbone, who not only stayed for the entire event, but whose band, 100 Monkeys, was the final of three groups to perform at the party.

And while some who stayed until the celebration’s final minutes tell OK! that by the end it resembled a “drunken frat party,” the planners made sure everyone would get home safely — All guests were given free taxi vouchers to ensure that no one would drink and drive.
